p. 18 of 18 CARE AND MAINTENANCE (IMPORTANT: Be sure to leave this page with the owner once installation is complete) Check and tighten hardware after 20 hours of operation. Periodically inspect and tighten hardware for the remainder of the unit s service life. IMPORTANT CLEANING INFORMATION Keep the enclosure components clean in order to prevent dust and dirt from forming an unattractive film. The life of your windows, doors, and roof panels depends upon following these care procedures: WINDOWS: 1) NEVER USE AN ALCOHOL-BASED PRODUCT FOR CLEANING. Do not use WIN- DEX, GLASS PLUS, FANTASTIC, etc. Use of these products will result in deterioration of the windows. 2) Wash with a mild soap or detergent using your bare hands to free or dislodge any caked-on dirt or other foreign particles. 3) A soft, grit-free cloth, sponge, or chamois may be used but only as a means of carrying water to the windows. 4) The interior should be lightly dusted (NOT WIPED) with a clean soft cloth or chamois. The cloth or chamois should be kept free of grit by frequent rinsing in clean water. 5) Grease and oil may be removed with kerosene. 6) Novus I and Novus II are recommended plastic cleaners and can be used to remove light scratches. DOORS AND ROOF PANELS: 1) NEVER USE AN ABRASIVE DETERGENT/VEHICLE CLEANER OR A WIRE BRIS- TLED BRUSH. Do not use any CITRUS BASED CLEANERS such as orange or lemon. Use of these products will cause the plastic to become permanently damaged. 2) Clean the plastic enclosure surfaces thoroughly with warm soapy water and a COTTON cloth or chamois. Be sure to use mild soap, specifically a dish liquid or equivalent. Clean in a light circular motion for best results. 3) Use EXTRA CAUTION when cleaning the interior of the enclosure. The interior is more sensitive than the exterior because the exterior has an extra coating for U.V. stability. 4) Remove grease and oil with mineral spirits and a COTTON cloth or chamois. The contents of this manual are the property of the owner. Be sure to leave with the owner when installation is complete.
